Used 2020 GMC Acadia for Sale nearRaleigh, NC

How much does the 2020 GMC Acadia cost?

Prices have softened 11.30% compared to this time last year, making it a favorable time to shop this model year.

There are 2,629 listings available, which suggests solid inventory for comparison shopping.

Is the 2020 GMC Acadia a good car?

Yes — the 2020 GMC Acadia earns a 4.9/5 user rating and a 7.00/10 expert rating. The model scores 8/10 across Look and feel, Form and function, and Technology.

Drivers consistently praise its smooth and quiet ride, spacious interior, and impressive features. The upscale Denali trim is especially well liked, and the cabin’s comfort and design come through strongly for family trips.

The trade-offs are that the price can feel high, cargo space could be better, and the tech updates do not fully erase the model’s value concerns. That fits the Acadia’s role as a practical three-row crossover with a roomy third row and easy-to-use technology, rather than a standout for excitement or bargain pricing.

Good and great deals account for 34.3% of listings, so you still have room to shop selectively.

Is the 2020 GMC Acadia reliable?

Owners rate it 4.9/5, a strong signal of long-term satisfaction.

The user feedback points to a dependable-feeling ownership experience, with drivers repeatedly highlighting comfort, smoothness, and a trouble-free everyday character. The expert evaluation also emphasizes refined, easygoing road manners and a powertrain that feels smooth and effortless in normal use.

GMC includes the first maintenance visit at no charge, which helps a little with early ownership costs. For used buyers, the main long-term risk is less about outright durability and more about whether you’re paying enough for the Acadia’s value equation to make sense.

What should I look for when buying a used 2020 GMC Acadia?

At 66.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a pre-purchase inspection, especially if you’re considering a higher-mileage example or one with prior bodywork. Focus on overall condition, evidence of repairs, and whether the features you want are actually present on the trim you’re shopping.

Key things to evaluate:

• Trim level: The Acadia comes in SL, SLE, SLT, new rugged AT4, and luxurious Denali trims. Base trims are more basic, while the Denali adds a more upscale look and feel, and the AT4 brings a more rugged personality.
• Powertrain: Lower trims use a 193-horsepower 2.5-liter four-cylinder, the SLT gets a turbocharged 2.0-liter four-cylinder with 230 hp and 258 pound-feet of torque, and AT4 and Denali variants use a 310-hp 3.6-liter V6. All pair with a nine-speed automatic.
• Safety package: The base Acadia SL includes blind-spot warning and rear cross-traffic warning, but forward collision warning and low-speed automatic emergency braking require at least SLT or AT4. Those features are part of a Driver Alert Package that also adds lane-departure warning, lane-keeping assistance, pedestrian braking, parking sensors, automatic high-beam headlights, and a head-up display. Enhanced automatic emergency braking is exclusive to Denali.
• Infotainment: Every 2020 Acadia includes Bluetooth, Apple CarPlay, Android Auto, and GMC Connected Services with a 4G LTE WiFi hotspot. Versions with an 8-inch touchscreen get a higher-resolution display, a simplified interface, and improved voice recognition.
• Fuel efficiency: The test vehicle returned 21 mpg in combined driving, and the Acadia’s powertrain is described as using stop/start and cylinder deactivation to help improve fuel economy.

Which 2020 GMC Acadia trim should I buy?

The 2020 GMC Acadia is offered in 5 trim levels: SL, SLE, SLT, AT4, and Denali.

Here's the short version:

• SL: This is the entry point, and it makes sense if you want the Acadia’s core space and tech without paying for extras. It includes the basic safety items, but you’ll want to step up if you want more advanced driver assistance.
• SLE: This trim is the straightforward value play if you want a little more equipment than the base model while staying focused on everyday family use.
• SLT: This is the best-value trim for many shoppers because it unlocks the turbocharged 2.0-liter engine and can be paired with more of the advanced safety equipment.
• AT4: Choose this if you want the rugged character and the standard dual-clutch AWD setup, along with the all-terrain tires and blacked-out appearance.
• Denali: This is the luxury pick, with the 310-hp V6, upscale trim details, and the most exclusive safety content, including enhanced automatic emergency braking.

The safety package is not fully standard across the lineup, so pay close attention to which trim includes the driver-assistance features you want.

Is now a good time to buy a used 2020 GMC Acadia?

The market looks selective-buyer friendly, with enough inventory and pricing softness to reward careful shoppers.

• Deal availability: 34.3% of listings are priced as good or great deals.
• Inventory: There are 2,629 listings available.
• Price trend: Prices have softened 11.30% compared with last year.
• Clean inventory: 66.9% of listings are accident-free.

If you find a listing below $19,621, that's toward the low end of the year-round range and worth acting on quickly.

What is the 2020 GMC Acadia's resale value?

The current average of $19,621 sits slightly below last year's $22,121.

That decline suggests the Acadia has already absorbed a meaningful amount of depreciation, which can help future sellers if they buy at the right price today. If you shop carefully now, you may have less downside left than a buyer who paid closer to the prior-year average.

The flip side is that resale value will still depend heavily on trim, condition, and equipment, especially because the model’s value proposition is tied to features rather than standout performance. Vehicles with strong owner satisfaction ratings, like this model year's 4.9/5, tend to retain buyer demand, which supports resale value over time.

Is the 2020 GMC Acadia safe?

The 2020 GMC Acadia earns five-star ratings in most NHTSA assessments, plus a four-star rollover resistance rating. The IIHS gives the SUV high marks in the tests it has completed.

It earns a 6/10 safety score from our experts.

Standard safety equipment includes a rear-seat reminder system, Teen Driver technology, automatic collision notification, SOS emergency calling, blind-spot warning, and rear cross-traffic warning. Forward collision warning and low-speed automatic emergency braking require at least SLT or AT4, and the more advanced automatic emergency braking system is exclusive to Denali.

The main caveat is that advanced driver assistance is not standard, so you need to shop trims carefully if safety tech matters to you most.

Should I buy a 2020 GMC Acadia or consider a different year?

If you're weighing the 2020 against nearby model years, here's how to think about it:

Choose the 2020 if:

• 34.3% of listings are priced as good or great deals.
• At 66.9% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.30% compared with last year.
• Owners rate it 4.9/5 — a strong satisfaction signal.
• The 2020 refresh adds bolder styling, a new AT4 trim, a turbocharged four-cylinder, a nine-speed automatic, and updated technology.

Consider the 2019 if:

• At $16,643, the 2019 costs less than the current year's $19,621 average.
• It feels more upscale than many other three-row midsize SUVs.

The bottom line: If you want the refreshed 2020 Acadia’s updated styling, broader trim mix, and stronger tech story, it’s the better all-around pick. If your priority is spending less up front, the 2019 can still make sense, especially if you value its upscale feel over the newer model’s changes.
